had to bridge pin 1 & 8 of U8 chip(on the back of the card) & U37 chip(on the front of the card) notice that their are 2 bios chips for each GPU core(like the 4870X2) pin 1 should have a dot on the IC or a arrow pointing to it, and pin 8 should be the exact oposite.

It happened a funny thing to me; I was going to resurrect my old x300se with this metode, but I had a problem with ati flash, "flash not detected, error 0fl01
I searched on the web, and there was a solution using flashrom.. The result, my 5670 was flashed with a x300se bios
I booted with a pci, and my 5670 wasn't found with atiflash, so I used this metode and my 5670 is now alive
The bios chip of the 5670 was on the back, so I didn't need to solder anything, I just made contact pin 1 with pin 8 with a wire, until de computer booted.
Also, if it helps someone, I will make a step by step guide, with photos
